Dauenbangh, Rockford, and Robert K. Unter, Roscoe, Ill., assignors to National Lock Co., Rockford, 11]., a corporation of Delaware Filed Sept. 17, 1962, Ser. No. 224,044 13 Claims. (Cl, 70208) The present invention relates to a novel lock and handle for a door of an enclosure and more particularly to a novel pop-out handle having a lock integral with the pop-out handle and latching means actuated by rotation of the handle to unlock the door of a vending machine or enclosure such as a garage, Walk-in cooler or other cabinet.

Of the commercially available vending machines, the majority do not have any handle which can be grasped by service personnel in opening the door or hinged front of the machine. Without such a handle, the door or front of the machine is liable to be opened by turning and pulling on the key used to unlock the machine with the result that the key breaks 013? or the lock is often damaged. Otherwise service personnel must grasp an undercut or protruding portion or edge of the machine for use as a handle.

With respect to enclosures such as garages, a protruding handle is normally provided to withdraw the latching bolts and a separate key lock must be operated with a key in conjunction with the handle to allow the handle to rotate. If the connection between the handle and lock is damaged or if either the handle or the key lock is inoperable, the unit cannot be operated.

An important object of the present invention is the provision of a novel pop-out handle and lock assembly where the handle is normally retracted to a position where it is unavailable for operation and cannot be grasped by an operator unless released by use of the proper key. Thus, there are no protruding parts capable of being twisted or damaged.

Another important object of the present invention is the provision of a novel handle where a key-operated tumbler lock is integral within the handle and upon actuation of a proper key in the lock the handle is released and automatically pops out to its advanced operative position to be grasped by the operator to release.

A further object of the present invention is the provision of a handle which when manually rotated will release the door latch so that the vending machine or other enclosure may be opened by the operator for any desired purpose.

The present invention also comprehends the provision of a novel motion transmitting connection which allows reciprocation of the handle between its advanced and retracted positions and rotation of the handle to actuate the latch means releasing the door of the enclosure.

For a garage door or walk-in cooler application the present invention further comprehends the provision of a handle on the interior of a door which is actuated by rotation of the pop-out handle, and a lost motion means to permit manual rotation of the interior handle independent of the pop-out handle to release the door latching means.

Further objects are to provide a construction of maximum simplicity, efficiency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

Referring more particularly to the drawings wherein is shown illustrative embodiments of the present invention, FIGS. 1 to 7, inclusive, disclose a novel pop-out handle and lock assembly 10 secured within the hinged door or other closure 11 of a vending machine such as used for vending candy, cigarettes, etc., and in which locking is effected by engagement of a locking part or strike 12 on the frame or cabinet of the machine by means of the latch bolt 13. The assembly is secured to the door 11 by suitable securing means such as screws 14 or the like.

The handle and lock assembly as shown in FIGS. 1, 2, 3 and 5 includes a spring-loaded handle 15 conformably received within a pocket or recess 16 in an escutcheon 17 shown as recessed or mortised within the door 11, it being understood the handle 15, when locked in pocket 16 by the spring lock bolt 27, cannot be rotated to unlatch and open the door. A central cylindrical housing 18 for the lock mechanism extends rearwardly and is part of the escutcheon 17 and terminates at the rear wall 19. A key-operated lock 21 of the tumbler variety is shown centrally positioned within the handle 15 and this handle and its lock assembly are slidably received within the housing 18.

Now more particularly referring to FIGS. 3 and 4 where the details of the pop-out assembly and lock are shown, the bolt 13 is shown in its engaging or locking position with the side latching lip or strike member 12. As seen in FIG. 7, a sloping camming surface 12 is formed on the extended latching end 23 of the bolt 13. The handle 15 has a central cylindrical body 24 extending rearwardly into the cylindrical housing 18 and stopping short of the rear wall 19 of the latter. Mounted within the cylindrical body 24 is the key-operated lock 21 having an eccentric pin 25 extending from the rear of the lock and received in an elongated recess 26 In locking position, the lock bolt projects through an opening 28 in the body 24 and an aligned opening 29 in the housing 18 and is moved or biased to its locking position shown in FIG. 3 by an expansible spring 31 having one end received in a recess 32 in the bolt and the opposite end seated in the body 24 in an opening 33 closed by a threaded plug. The bolt has a camming surface 34 to engage the interior of the housing 18 and retract the bolt as the handle is moved from its advanced position to its retracted position, permitting the handle to be locked without using the key.

At the rear of the body 24 is an annular groove 35 defining a central positioning projection 36 for receiving one end of an expansion spring 37 in the annular groove 35 and the opposite end bearing against the flanged end 38 of the bolt bushing 39 which extends through an opening 41 in the rear wall 19 of the housing 18. The spring 37 tends to drive the cylindrical body 24 of the handle and force it outwardly to the advanced or pop-out position shown in FIG. 4. In this position the key has been turned to release position and the handle has popped out. However, upon release of the key, the lock bolt 27 is spring-biased or driven upwardly with its projected end and its camming surface 34 extending through and beyond the opening 28. In this released position (dotted lines in FIG. 3), the eccentric pin and key are springactuated and returned to the position shown. It is to be noted that the key is removable only in the locked position of FIG. 3.

The bolt bushing 39 is retained in position by a resilient O-ring 42 of natural or synthetic rubber received in an annular groove 43 adjacent the wall 19 of the housing, although a metal retaining ring could be used in place of the O-ring 42. The bushing 39 is externally threaded at 44 for a substantial portion of its length to adjustably mount the interiorly threaded latch bolt 13. A set screw 45 located in the side of the latch bolt positions and secures the bolt onto the bushing at the desired adjustment relative to a strike or other engaging surface on the member 12 which is a part of the fixed cabinet. The bushing has a central square opening 46 in the forward flanged end 38 opening into an enlarged circular opening 47 extending to and through the rear end 48 of the bushing.

The projection 36 on the body 24 which is a part of the handle 15, contains a square blind opening 49 adapted to conformably receive one end of a square spindle 51 extending through the opening 46 of the bushing 39. An anchoring pin 52 is inserted into aligned openings in the projection 36 and spindle 51 to secure the spindle to the cylindrical body 24 of the handle 15. On the opposite end of the spindle 51 is an enlarged rounded head 53 which conformably slides within the cylindrical passage or opening 47 and limits longitudinal movement of the handle 15, the body 24 and the spindle 51 due to engagement of the head 53 and its shoulder 54 with the junction of the square and cylindrical openings 46 and 47, respectively.

In operation, with the handle 15 in its retracted locked position and the door or closure latched as shown in full lines in FIGS. 1, 2 and 3, a proper key 56 is inserted in the lock 21 and turned actuating the eccentric pin 25 to retract the bolt 27 against the action of the spring 31. When the bolt 27 is withdrawn from the opening 29 in the housing 18, the spring 37 actuates the handle 15 to its pop-out or advanced position shown in FIG. 4. The enlarged head 53 moves in the cylindrical passage 47 and the square spindle 51 moves in the passage 46 until the peripheral shoulder 54 on the round head 53 abuts the limiting shoulder 55 in the passage 47. The handle 15 is then grasped by the operator and rotated counterclockwise for approximately 90.

Turning the handle 15 also rotates the cylindrical body 24 of this handle and the square spindle 51 secured 7 thereto by the pin 52. As the opening 46 in the flanged end 38 of the bushing 39 is square and complementary to the spindle, rotation of the spindle 51 rotates the bushing 39 and the latch bolt 13 (FIG. 5) to release the door 11 from engagement with the surrounding frame or cabinet 12 so that the released door may then be swung open. A stop 57 is contemplated in the housing 18 cooperating with the flanged end 38 of the bushing 39 to limit rotation of the handle and latch bolt through approximately 90 for this operation.

To close and latch the door 11, the movements are reversed with the door being moved to a closed position and the handle 15 rotated clockwise through approximately 90 to rotate the bolt 13. In this movement the camming surface 22 on the end 23 of the bolt engages the locking lip or strike member on the frame or cabinet 12 and the door and locking lip on the machine are urged together to a fully closed and latched position. Then the handle is pushed inward against the action of the spring 37 and the camming surface 34 on the lock bolt 27 engages the housing 18 to retract the bolt into the body 24. The elongated slot 26 in the bolt 27 allows movement of the bolt relative to the pin 25 of the lock 21 during this closing movement. This permits the door to be locked Without having to use a key. Inward movement of the handle continues until it is received in the recess 16 of the escutcheon 17 which then prevents handle rotation for unlatching the door, and the bolt 27 is driven or moved outwardly into the opening 29 in the housing 18 which retains the handle in a locked position as shown in FIG. 3.

FIGS. 8 and 9 disclose the utilization of the pop-out handle and lock assembly 10 for a garage door or similar member for an enclosure where the door is of the overhead variety travelling on laterally positioned tracks. The handle and lock mechanism shown in these figures is substantially the same as that disclosed in FIGS. 1 to 5 except the lock mechanism 21 is located off-center in the handle 15 and the latch bolt has been replaced by an interior handle 58.

The escutcheon 17 housing the handle 15 is secured to the door 59 by suitable fastening means 14 and the cylindrical housing 18 extends through the door and contains an identical lock and pop-out assembly as previously described. The bushing 39 has a smooth exterior surface and a sleeve 61 slips over the bushing and is actuated thereby. The handle 58 is integral with or affixed to the sleeve 61 and the sleeve is retained on the bushing by a locking pin 62 extending through and secured to the bushing 39 with the ends of the pin extending beyond the bushing to prevent the sleeve 61 from being removed from the bushing. A pair of opposed slots 63 are cut into the outer edge of the sleeve to receive the pin 62 with the slots extending around the sleeve over an arc of approximately 60. Slots 63 permit the inside handle 58 to be turned to open the door, even though the outside handle 15 is securely locked in the recess 16.

The interior handle 58 is formed of a substantially rectangular member or body 64 having the sleeve 61 extending centrally therethrough and adjacent one end. A handle portion 65 having flanged rounded edges 66 depends from the member 64 to be grasped by the operator. The member 64 has a pair of openings 67 positioned at opposite corners of the member and each adapted to be connected to one end of an actuating chain, wire sash cord or other suitable connecting means 68 having its other end connected to a spring bolt 72 of the door latch means.

The door latch means includes a bracket 69 secured adjacent each edge of the door 59 by screws or other suitable means 71 (only one latch means being shown in FIG. 9 although two may be used). A spring bolt 72 driven outwardly to latching engagement by an expansion gated slot 74 therein cooperating with a rivet or pin 75 mounted in the bracket to limit longitudinal movement of the bolt. A camming surface 76 is blanked on the end of the bolt 72 and angularly disposed to the latching surface 77 on the bolt cooperating with a strike 78 on the enclosure for the door for preventing raising of the door except when the latch bolt is retracted. The disclosed latch may be of conventional design.

To allow freedom of movement for the pop-out handle 15, the enlarged rounded head 53 has a slot 79 cut therein to encompass the locking pin 62 when the handle is retracted and to allow movement of the head and its associated spindle 51 when the handle is popped out.

The latching mechanism for the overhead door 59 is capable of operation from either side of the door. From the outside, the key 56 is inserted in the lock 21 to withdraw the lock bolt 27 and allow the handle 15 to pop out. Turning the handle counterclockwise causes the pin 62 to bear against edges 81 of the opposed slots 63 and rotate the sleeve 61 which is part of the interior handle 58. Rotation of the handle as shown in the dotted lines of FIG. 9 causes actuation of the chains or cords 68 to withdraw the spring bolts 72 to release position, wherein the latching surfaces 77 are withdrawn from engagement with the strikes 78 and the door may be raised.

When the door is lowered, the camming surfaces 76 engage the strikes 78 causing the spring bolts 72 to be cammed inwardly or retracted so the door can be closed and the spring bolts 72 urged to their normal latching position shown in FIG. 9 through the action of the expansion springs 73. This returns the interior handle 58 and the outer handle 15 to normal vertical position and, if the user desires, the latter is retracted into the recess 16 in the escutcheon 17 and locked through the locking bolt 27, or the outer handle 15 may be left in the extended position, free of recess 16 and then used only as a latching handle whereby the door may be opened without the need of using the key 56. To lock, all that is required is to push the handle in as explained above.

To unlock the door from the interior, the handle portion 65 is grasped and rotated in a clockwise direction as seen in FIG. 9 to withdraw the spring bolts 72 and release the door from the strikes 78. The slots 63 in the sleeve 61 having a length of an arc of approximately 60 allows the handle 58 to rotate independent of the bushing 39 and locking pin 62 for interior actuation.

In both of the disclosed and above described embodiments of the present invention, the door or closure is adapted to be opened from the exterior by insertion of the proper key and turning of the key through an arc of approximately 45 to retract the spring lock bolt 27, whereupon the operating handle 15 is released and springs or pops out of its escutcheon 17. The handle is then free to turn and when turned unlatches the door from a strike or part on the encompassing frame to permit the door to be opened.

In FIG. is disclosed another embodiment and application of the present invention to the door 11 of a cabinet 81 such as a walk-in cooler or the like having a sealing gasket 82 adapted to be compressed between the door and cabinet. In this embodiment, the structure of the pop-out handle assembly is identical to that shown in FIGS. 1 to 9, inclusive, except for the omission of the stop 57 in the housing 18 whereby to permit the handle to rotate through at least 360, and the removal of the locking or latching bolt 13 shown in FIGS. 1, 3 and 4.

In this form of the invention the inner threaded portion of the bolt bushing 83 is screwed directly into an internally threaded strike or fixed nut 84 in a housing in the cabinet 81. Thus latching is eifected by the threaded bolt bushing 83 engaging the nut 84 and compressing the gasket 82. This bolt bushing 83 is similar to the bolt bushing 39 except the flange 38 is devoid of any stop notch to permit rotation through at least 360. The threaded opening 85 within the fixed nut 84 has a countersunk opening 86 to guide or direct the bushing 83 into the fixed nut and threadedly engage the latter shown within a housing or fixed part 87 of the cabinet.

This embodiment operates in a manner similar to the embodiment of FIGS. 1 to 7 except that when the handle 15 is popped out, it is grasped by the operator and rotated counterclockwise to retract and disengage the threaded bushing 83 from its nut or strike 84. When closing and locking the door, the bushing 83 is moved to engage the strike 84 and the handle 15 rotated clockwise to draw the door and cabinet together and compress the gasket 82, thus sealing the enclosure. Then the handle 15 may be retracted into the escutcheon 17 to lock the handle against rotation.

While the pop-out handle and lock assembly has been shown and described as being advantageously applicable to a vending machine, garage door, Walk-in cooler or the like, it is not our desire or intent to unnecessarily limit the scope or utility of the features of the invention by virtue of these illustrative embodiments.
